Epanet Time Chart

An EPANET Time Chart shows simulation information as a function of time elapsed in the simulation. This simulation must have a start date/time different from the end date/time of the simulation and an interval different from zero, in order to produce results (See the topic Epanet / Intervals to learn more).

A temporal simulation graph has the following properties:

• Identification
  • Description - Use a friendly description when the item name is not enough
  • Name - Item Name
  • Priority - Information about the current state of the item. It might be: Neutral: no problem Warning: some problem, but that does not prevent the use or calculation Critical: Some issue that prevents the item from being calculated or used
  • Object Type - Object Type
• Object
  • Error Evaluation - Data evaluation result
    The data provided is evaluated so that the graph can be drawn. If it cannot, one of the errors below may appear:
    • EPANET is not calculated - Use the command EPANETCALC to calculate
    • Insufficient Data - Missing data items in series worksheet - add at least one item to worksheet:
      
      
    • Range - indicates that the graph range is not contained in the simulation range:
      • The graph start date/time is less than the simulation start date/time
      • The graph end date/time is greater than the simulation end date/time
      • Chart start date/time equals Chart end date/time
    • Some of the time series have problems - note which series is marked with a red dot :
      
      
• Chart - indicates the start and end of the chart
  • End Date - Date the chart ends
    It must be less than or equal to the end date of the simulation
  • Start Date - Date the chart starts
    Must be greater than or equal to the start date of the simulation
  • End Time - Time the graph ends
    It must be less than or equal to the end time of the simulation
  • Start Time - Time the chart starts
    Must be greater than or equal to the start time of the simulation
  • X axis - X axis format
    It might be:
    • Date - data is shown on their respective dates
    • Elapsed time - data is shown relative to the start of the simulation in days, hours, minutes or seconds

For a graph to be plotted, data must be provided. This data can come from:

• Nodes - the EPANET Nodes
  It is necessary to select the network node that you want to monitor
  • Demand
  • Hydraulic Head
  • Pressure
  • Quality
• Links - the EPANET links
  It is necessary to select the link of the network that you want to monitor
  • Flow
  • Speed
  • Head Loss
  • Quality
  • Status
  • Configuration
  • Reaction Rate
  • Friction Factor

To create a temporal plot, use the command SEPANETPLOT
